CAR-COUPLING AND TRAIN-PIPE COUPLING COMBINED.

SPECIFICATION forming part of Letters Batent No. 724,004, dated March31, 1903.

Application filed June 23, 1900. Serial No. 21,355. (No model.)

To all whom it may concern:

Be it known that I, DEE T. GRANBERY, a

citizen of the United States, residing at Mem phis, in the county ofShelby and State of Tennessee, have invented certain new and usefulImprovements in Car-Couplings" and Train-Pipe Couplings Combined, ofwhich the following isa specification.

This invention relates to car-couplings and train-pipe couplingscombined; and it consists in certain improvements in the construction ofthe same, as hereinafter described and claimed. f V

In the accompanying drawings, Figure 1 is a plan view of one of thetrain-pipe-coupling heads. Fig. 2 is a transverse section taken on lineX X of Fig. 1. Fig. 3 is a plan view of the under side of apipe-coupling head with other details. Fig. 4' is an under side-viewshowing two pipe-heads uncoupled. Fig. 5 is a side view showing one sideof a drawhead of the car-coupling and of the pipe-coupling headinconnection. Fig. 6 is a side view showing the sides of the draw-head andthe pipe-coupling head opposite to those shown in Fig. 5. Fig. 7 showsin horizontal section the pipe-coupling heads as coupled. Fig. 8 showsmodifications in the construction of certain mechanism connected withthe pi pecoupling heads.

E indicates the pipe-coupling heads, each of which is formedsubstantially as shown in Fig. 1, conforming to each other on theirinner faces to form a close joint, (see Figs. 7

and 1,) each head having a curved surface or convexity e at its freeend, then a plane surface 6 next to which is a convexity a and next tothe latter is a concavity 6 Each pipe-head having the sides f, a seat isformed by the concavity e and the side pieces to receive the convexportion 6 of the joining pipehead when a coupling of the headsis-edected. Tubular passages g are made in each of the pipe-heads E,three passages in each head being shown, said passages extendingrearward from corresponding points in the planes e of the pipe-heads tothe rear ends of the heads. The passages g of one head connect withthose in the other when the two heads are coupled, as seen in Fig. 8.From the tubular passages g extendibranch pipes g for conveying steam,heat, and air from car to car and for the purpose of a whistle, theconhection of pipes of one car with those of another being formed ofelastic hose, A .pring-rod g is provided for each pipe-head,the latterbeing recessed at N, showing the-sp'ring h. v

The pipe-head extends rearward into a casing 0, in which the spring-rodalso has'bearing, so that the pip'e-head-has somewhat of a movement insaid casing. "The branchpipes g are each provided with a valve h, havinga stern 71 which is? connected with a'rod 'i, the latter being connectedwith a' horizontal rod is, which extends forward and is con nected .withthe spring-bufferB, so thatsaid valves are operated bythe actionof saidbufi er.

F indicates a rectangular frame, one being pivotally mounted on eachpipe-head, the connection being by a bolt or rod m, passed through thehead, which latter extends through said frame. Another rod m is mountedin the frame F, said rod extending across it near the outer side of thepipe-head. Springs m, one of which is connected with each pipe-head, areadapted to bear against the frames F and hold them in position forcoupling. (See Figs. 1 and 2.) Guard-horns m carried by the frames F,serve to bring the pi pe-heads to their proper relative position in casewhen two cars are coming togetherithe two heads are not exactly on thesame level. The guard-horns also serve to press backward the frames Fwhen uncoupling, as the rods 19 move against said frames, as hereinafterstated.

To the outer side of the casing O is movably secured in suitable'bearings a rod or shaft 10, adapted to be moved longitudinally and.

to bear: against the frame F. (See Figs. 3

and 6.) To the shaftp is securedat z one end of a connecting-rod p, theother end of said rod being connected with an arm p of a shaft .10 whichis mounted in an'oifsetp of the casing O and extends to the oppositeside of said casing and has an arm 10 which extends upward and has alink connection with a branch .9 of the horizontal shaft 0, which ismounted in bearings on one end of the cartruck. (See Figs. 3 and Mountedin a recess J in the outer sideof each pipe-head is a spring-lock m,which is connected at the forward end with'the pipe: head by a bolt 0,the rearward end ofthe v lock being made fast to-a bar g, which extendsdownward and is then turned under the pipe-head and is connected "with arocking bar 0, which is on the extended end of the rod 711, whichconnects the frame F with the pipe-head. The spring-lock m is formedwith a catch it, which is projected for locking by a spring 0" in therecess J. When the pipeheads are coupled, the catches a of the locksconnect with the rods 'm' of the frames F, (see Fig. 7,) and said framesare held in position by the shafts p and by the springs m Circular disks0- are eccentrically connected with the rocking bars 1' by the rods m,said disks having limited rotative movements, such movements beingtoward and against the projectiqns 'u on the bars 7".

G indicates a bent lever, which is pivoted at 'w to the offset 1) of thecasing O and has a hearing or guide to. The lock bar q is connccted by achain 12 with the bent lever G, and a disk 2' is connected with saidbent le-. ver by connecting-rod a The rearward end of the lever G isconnected by a chain P with a retractlug-spring Q to return the lever toits position after its movement. Said lever G is also connected by achain S with the branch .9 of the horizontal shaft C.

'1 indicates a chain which connects a spring with the truck-bolster tohold the pipe-coupling in position when the train is rounding curves.

The draw-head A, having tail-pin R, extends between the truck-timbers,to which is secured by bolts the upper bearing-plate 1, the lowerbearing-plate 2 being connected by 4 a bolt 3, extending downward intothe buffer and having thereon a spring 4.

A copper plate (marked 5, see Fig. 5) is set in the pipe-coupling headfor the purpose of suitable attachments for electrical connections ofcars for purpose of lighting and also for signaling between theconductors and other employees.

As will be seen, the car-coupling may be operated to uncouple by meansof the vertical lever 61 or by lever c and may be uncoupledautomatically by the action of the spri ngbuffer B and levers d and dand by movement of the branched shaft C, which has a handle at eitherend for such purpose, the connections are such between said shaft andthe lever d of the car-coupling and the lever G, connected with thepipe-coupling head, that the uncoupling of cars and train-pipes may besimultaneously effected. cars come together, the coupling of the carsand also of the train-pipes is automatic.

In Fig. 8 are shown certain modifications in the construction of certaindetails shown in Figs. 5 and 6. The bent lever G has a forked end toreceive the connecting-rod n and is secured thereto by an eyebolt, whichis connected by a chain c with the lever 1".

As will be seen, the operation of uncoupling is eifected by a partialrotation of the shaft 0 through its branches .9 and 8, one of which isconnected by a chain with the rearward end of the bent lever G, theforward end of said lever being connected by a chain with the lock-bar qand by a rod n with a When two circular disk 9", which is eccentricallyconnected with a rocking bar 0', the disk to 1'0- tate in the directionof the arrow 00 in Fig. 3 to the stop 0 on the bar '1" of an oppositepipehead. Vhcn the shaft 0 is turned by either handle, so as to moveforward both of the arms 8 s, the rearward end of the lever G is movedforward and the forward end of said lever is turned backward by thedrawing of the chain P, connected with the arm 3 of shaft G. The disk 0'is partially rotated by the rod 01 The forward end of the lever G beingconnected by a chain with the bar q, the latter is drawn inward enoughby the movement of the lever to move the spring-lock with its catch 11into the recess J out of connection with the bolt on. The shaft 19 whichextends across the casing O, by its chain connection of the arm 11 andwith the arm 13 and connectingrod 12, connected with the bar 1),actuates the latter, moving it forward to engage the frame F and movesaid frame to position for uncoupling.

1 claim 1. The combination, with a pipe-coupling head, of a easing intowhich said pipe-head extends, a two-arm shaft carried by said casing,one arm of said shaft being connected with a longitudinal rod adapted tomove against a frame pivotally mounted on said pipe-head and the otherarm of said shaft having a link connection'with a branch of aborizontalshaft 0, carried by the car-truck, and a vertical lever pivotallymounted in a drawhead of the car-coupling and connected bya rod withsaid branch of the shaft C.

2. The combination with a pipe-head having a recess J in its outer side,of a springlock secured therein by a bolt at its forward end andprovided with acatch 'n, a bar q connected with said lock and extendingdownward and under said pipe-head, a rocking lever provided with aprojection U, carried by said pi pe-head and connected with bar q, acircular disk eccentrically mounted and connected with said rockinglever, a bent, pivoted lever one end of which is connected by a chainwith a branch of the shaft 0, said lever also having a link connectionwith the spring-lock, and a rod connecting said bent lever-with saidcircular disk, substantially as and for the purposes described.

3. The combination with a pipe-head of a pivoted rectangular frameprovided with a crossing rod, a spring-lock mounted in a recess of saidpipe-head and provided with a catch 12, adapted to connect with acrossing rod of asimilar rectangular frame connected with an oppositepipe-head, when two pipeheads are coupled, substantially as and for thepurposes described.

In testimony whereof I affix my signature in presence of two witnesses.
